UNDERSCORING-ATTACHMENT FOR TYPE-WRITERS.

Specication of Letters Patent.

Applieatonyled October 2, 1915. SerialNo. 53,8137.

To allzu/tom it may concern:

' Be it known that I, HAROLD F. VADE, a

portunity, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Underscoring Attachments` for Type-Vriters, of which the following is a specification.

An object of my invention is to provide an attachment for'typewriters, consisting Iof a separate underlining character', together with means to operate the same iiidependently of the operation of the remaining portions of the mechanism.

A further object is to construct theparts in a manner that the underlining character may be brought to a set position in a relation that as the letter or other character desired to be underlined is brought tothe printing position, the underlining character' is simultaneously given printing contact.

Yet another object is in the provision of a locking means to be brought into operative relation' upon shifting of the underlining chiricter to the printing' position to hold the same in a position to beoperated upon printu ing of the letter characters, until manually released.

A still further object is to arrange the parts in such a manner that the operation of the underlining character will be equally eilicient in the use of the letter keys in either the lower case or the shift positions.

With other objects vin view, which will be referred to, myV invention consists in the particular construction and novel arrangenient of parts which will hereinafter be described in connection with the accompanying drawings and more 'particularly pointed outY in the appended claims.

In the drawings V Figure 1 is a diagrammatic plan view of a standardtypewriting machine with my invention applied thereto. i

Fig. 2 is a diagrammatic sectional view through the disclosure in Fig. 1 to better illustrate the arrangement of the operative parts.

Fig. 3 is a fragmentary perspective View of the means for locking andretaining the device in the operative relation.

Fig. 4 is a detail view ofthe character carrying bar.

Fig. 5 is a view similar to Fig. i of one of the `type carrying bars of the machine showing slight modifications which it may b e necessarv to make therein.

In the adaptation of the invention as illustratedl in the accompanying citizen of the United States, residing at Op:

drawings, a machine constructed along the lines of the standard Underwood typewriter is disclosed, although it will be understood that this is only one type of machine to which my iii `vention may be applied and with which the saine may be use e `The machine comprises the frame l, in which the type bars 2 carrying the type characters 3 are mounted in the usual inanner to be operated by the .operating keys 4. The platen 6 is mounted'iafthc usual manner, and as all of these parts are of standard form and'arraiigeinent, the same are illustrated 'only diagraminaticallyI in the drawings accompanying this application.

Preferably at one end of the frame 1 an?` additional operating hai` 7 ismounted pivoted on the support 8 by which the remaining bars are pivotally mounted in the machine, and this operating har has the free end thereof extended upwardly` and provided with the operating. key'fwhich is conveniently placed in the key hoard of the machine. In the form of machine. illustrated, the type bars 2 have the bases 10 thereof provided with the double hooked formation by which the sockets 11 and 1:2 are formed, and these type bars are placed on the mounting wire 13 by having the same positioned within the sockets 11, links 14 being positioned in the sockets 12 and connected with the operating hars 1,5 of the operating keys At a point adjacent the positioning in the frame of the operating bar. 7, an additional character 'carrying bar 16 is mounted h v having the. mountingwire 13 received yin the socket 17 of the base thereof. and tliiscarrying bar 16 is operatively connected with the operating bar i by a link 18 which is looped over the bar 7 and through the' socket 19 of the base of the character carrying bar.

The usual ribbon guide 20 'is provided on the machine adjacent the platen roll 6 on which the paper is carried, and the character carrying bar 16 has the underscoring type 2l fitted to the free end thereof and constructed in a manner to fit and be received between the side members of the ribbon guide 20. As lis better illustratedI in Fig. 1, the underscoring type is made with a double face, that is, this 'type is provided with two i'inderscoring characters, one of which is positioned to beopera'ted when-the ing characters are carried forward with 16'as this bar is actuated to bring the un derscoring character to the operative position, to cause a slight return movement of the bar 16 and to thus raise the underscoring character 2l from a printing engagement against the ribbon.

vWith the mechanism asl hereinbefore described, it is possible -to underscore any of the type characters which may be printed 'in either upper or lower case by the machine subsequent to the printing thereof, and as no connection is provided between the operating bar or the character carrying bar to the carriage shift, this underscoring of the.' type character does not move the machine from a position to have the next type character printed run in the` proper reading sequence. As hereiiibefore stated, it is one of the objects of my invention'to so construct the underlining mechanism that the same will operate simultaneously `with the printing of the type characters, and to this end, theunderscoring characters are made comparatively thin in their transverse extent from the printing faces, and the faces of the type characters 3 are provided with the trait?L verse notches 2l to iit over these type characters and at the same time to permit proper and a sutlicient equal engagement of the type characters against the ribbon to accomplish a printing action. That the underscoring characters will be retained in a position between the side vmembers ofthe ribbon guide 20 to b'e engaged as the various type characters 3 are brought to the printing relation, the operating lever has a lug 25'formed toextend from one side thereof and a retaining sprinflr 26 is mounted on the frame adjacent the formation of this lug to have one end thereof free to engage with the upper face of the lug 25 as thev operating bar T is depressed and to thus hold the underscoring character at a position between the side-'members of the ribbon guide 20, where the characters are held from conbring the type characters 3 to the printingrelation, the underscoring characters are engaged in the notches 24 and the underscorthe type character to print simultaneously therewith. W'hen it is desired to release the underscoring means. the release key 27 carried by the swinging lever 28 is pressed, and as this lever 2 8 is pivoted at 29 to the frame and as the free lend 30 thereof is engaged with the free end of the spring 25, rocking of the lever 28 about this point of pivot 29 causs the end 30 to displace the spring 26 from its position of retention upon the top 0f the lug 25 and the underscoring character carrying bar 16 returns to its normal position.

The attachment may be used to print single underscoring character subsequent to the printing of any one of the typecharacters without displacing the carriage shift, and by operating the release key 27, the

parts are restored to normal, or as has been hereinbefore set forth, the underscoring operating key 9 may be depressed to a position where the retaining spring 26 becomes operative, and with the parts in this relation, the standard lcharacters may be printed and underscored simultaneously and when the lower case characters are used, the

lower of the two underscoring characters will be engaged in the lower notch 24 of the type characters 3; then as the shift key of the typewriter is operated to set the machine to print the upper case characters, the upper underscoring characterl 21 will be brought to the operative relation, and an equally efficient result will be obtained.

While I have herein shown and described one specific forni of my invention, it will be understood that slight changes might be ,resorted to in the formation and arrangement of parts without departing from the spirit i and scope of Vthe invention as claimed, and hence I do not wish to `be limited to the eX- act construction and details herein described in the specification.

lVhat is claimed is:
